An exclusive recording from a popular hot spring resort featuring a rejuvenation massage session. This massage treatment involves carefully stimulating acupressure points and lymph nodes around the prostate, testicles, and anus to restore youthful vitality in men. It is said to boost stamina and improve sexual function. However, one side effect is that the treatment may cause an unexpectedly strong erection, creating a difficult situation to handle. Fortunately, for an additional fee, the masseuse will take care of the issue properly. A unique experience offering both mysterious benefits and surprising drawbacks.
